OnLeaks indicates that HUAWEI is currently testing two different P20/P20 Plus prototypes, and the biggest difference between the two versions is the Home button. One of the prototype Home physical buttons is at the bottom of the screen, and the other prototype is not a physical button.
Unfortunately, after several days of investigation, HUAWEI is unable to confirm the final decision. Therefore, the HUAWEI P20 Plus version of OnLeaks shows no Home button. OnLeaks also indicates that subsequent rendering will be provided with the Home button.
According to the current information, the size of the machine is 155.3 x 74.2 x 7.7 mm (the camera thickness is 9.8mm), and the screen size is about 6 inches.
